savewav: Save a .wav file

Description

Save sound data as .wav file

Usage

savewav(wave, f, channel = 1, filename = NULL, rescale = NULL, ...)

Arguments

wave

an R object.

f

sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave.

channel

channel of the R object, by default left channel (1).

filename

name of the new file. (by default the name of wave).

rescale

a numeric vector of length 2 giving the lower (negative value) and upper (positive value) amplitude limits of the .wav file to be exported.

...

other arguments to be passed to writeWave

Details

This function uses three functions from the package tuneR: Wave, normalize and writeWave.

export.

Examples

# NOT RUN {
require(tuneR)
a<-synth(f=8000,d=2,cf=2000,plot=FALSE)
# the name of the file is automatically the name of the object
# here: "a.wav"
savewav(a,f=22050)
unlink("a.wav")
# if you wish to change the name, use the 'file' argument
savewav(a,f=22050,file="b.wav")
unlink("b.wav")
# if you wish to change the amplitude of the file, use the argument 'rescale'
# this will turn down the volume of a 16 bit sound
# which amplitude was originally ranging between -2^15 and +2^15
savewav(a, f=22050, file="c.wav", rescale=c(-1500,1500))
unlink("c.wav")
# }
